When a gearbox, pump or motor starts weeping lubricant around the shaft, the DBH 5223Sil seal is often the part that has reached the end of its service life. This radial shaft seal sits on the rotating shaft and presses against the housing bore, holding oil or grease inside while keeping dust and water out. Its Lz design means a single lip with a spring, and its dimensions are 45 mm shaft, 65 mm housing and 10 mm height. MR Industrial Accessories supplies this brand and helps you match the right seal to your equipment.

Reading the code is the fastest way to confirm a match. The DBH 5223Sil designation belongs to the DBH 5223 series, a family of standard-section seals built for metric shafts. The three figures that follow describe the fit: shaft 45 mm, housing 65 mm, height 10.00 mm. If those numbers line up with your shaft and bore, the seal is the correct size for the seat.

You will find seals in this size range on gearboxes, centrifugal pumps, electric motors, rollers and other transmission equipment. In every case the job is the same: close off the path where lubricant would otherwise escape, and block contaminants from working their way in. Equipment built around a 45 mm shaft and a machined 65 mm housing is where this seal typically appears, and it is designed to be replaced without special tooling.

Installation rewards a little care. Clean the shaft and the housing bore and check both for burrs, nicks or scoring. Coat the lip with the same oil or grease the equipment runs on, then seat the seal square to the shaft, applying force to the outer edge rather than the lip itself. If the shaft shows a wear groove, consider a seal that places the lip in a different position along the shaft.

Speed, temperature and lubricant type all influence which seal is right for a given application, so it is worth confirming those details before ordering. If you need a cross-reference, send the original code along with the shaft, housing and height measurements and a photo of the part. From there we can look through the DBH line or other compatible options and point you to a workable replacement.
